Now that Kristen Stewart and Robert Pattinson are apparently no longer an item, the latter 'Twilight' star has been getting around. That's not to say R. Patz is dating every woman he's pictured with (although he and Katy Perry definitely seemed to have something going on for a bit), but the latest woman who has allegedly fallen under his spell is Riley Keough, the granddaughter of iconic singer Elvis Presley.

According to the Daily Mail, the British actor was snapped by paps as he drove around Los Angeles with Keough in the front seat of his car over the weekend. Apparently, after they hit the town with a ping-pong table in tow, the duo head back to hang at Pattinson's mansion in Los Feliz and play a few games. Although it's still very early to draw any conclusions, sources are saying that R. Patz and Keough are officially dating.

What makes this romance rumor all the more interesting is that Keough co-starred in 'The Runaways' with Pattinson's famous ex, Kristen Stewart, who was busy getting ready to attend fashion week in Paris over the weekend. (In case you're curious, Keough plays Marie Currie in 'The Runaways,' sister to Dakota Fanning's Cherie Currie.) She's also remained friends with Stewart -- maybe how she got to meet Pattinson in the first place? -- and was seen at the actress' birthday party in Mexico this past April.

Keough was previously engaged to 'Magic Mike' actor Alex Pettyfer, and has also been linked to Ryan Cabrera and Jonah Hill. She is the granddaughter of Elvis and Priscilla Presley, and the daughter of Lisa Marie Presley and Danny Keough.

We wonder if K. Stew is feeling scorned by her 'Runaways' co-star and ex-BF. It's gotta burn at least a little bit, right?

And doesn't Riley resemble Kristen in the facial area? Kinda creeeeeeepy.
